What size
what size tires you got on? I got a lift and 35s and I got 15mpg ? going 500miles driving through Texas. Stayed at 70mph on Eco. Also got 3 dogs, tow hitch carrier, and roof rack luggage.
I would search for Xpel shops around your area. I found one in Austin and I paid $3019 for full front and a-pillar PPF with window tints all around. Sometimes you can get promo codes from influencers that take 10% off. Full PPF for the entire truck was upwards towards $7-8k.
